n number of such movement h'o'lders fa re :in use today bi'itdependlargelyonadjustments'iand adjustment *devices that are. not positive =intheir operations. Some of these movement :holders relywn friction,others on springs andstillothers on both springs and irritation. ofcourseineither springs norrfriction give anyipositiveadjustment.

There is another class of such holders inwhicha single pair of "jaw-sare positively moved toward and from each other: ln 'this class ofmovemen't holders-spaced means, which are fixed on such jaws, are usedto grip the movement at the spaced points on opposite "sides. *Suchholders do not provide for the positive adjustment of such jaws.

The principal object of the present inyen tion is to provide a movementholder wherein four jaws are employed which are arranged in pairs. andwherein positive adjustment may be made to the relativepositionsnfithese jaws;

:Aseconddmportant .obj ect.of*the:invention1is to provide a movementholder'which maybe "used tor the smallest type .of Wristwatches, $013constructed in .proper .size, may be used v for Watches .of largerdimensions. .5 third important object :of the invention is to provide amovement holder wherein the jaws are so constructed and arranged as tosecurely hold a. movement without the possibility of its slipping outand in such manner that, under the skill of the watchmaker, no unduepressure or distortion will be given to the lower plate of the movementwhich is gripped by the holder.

With the above and other objects in view as will be hereinafterapparent, the invention consists in general of certain novel features ofconstruction and combinations of parts presently to be specificallydescribed with relation to the accompanying drawings, and particularlyclaimed,

Also the 1 1o ds 5115 will; Lander-movement rofstheipairsv of ijaws it-award: each other, pass into the cut away portionsand thus not interfere with the closing closely of the jaws l6. On topof the body of each of these jaws is a lug 20 having an upwardlyextending and slightly overhanging gripping portion 2|. Thus there isprovided four jaws and in order to move the jaws of each pair toward andfrom each other a screw 22 is fitted in a threaded opening in one lug 20of each pair and this screw has a cylindrical portion 23 revolublyfitted in the other lug 20 of the pair and provided with a head 24 onthe outer side of the lug and a collar 25 on the inner side of the lug.Thus rotation of a screw 22 will move the jaws l6 of the pair toward orfrom each other as desired.

It will now be obvious that not only may each pair of jaws be adjustedpositively toward the other pair but also that the jaws of each pair maybe adjusted positively toward and from each other. Furthermore it willbe observed that for irregularly shaped watches the jaws of one pairmaybe adjusted at a different spacing than the I jaws of the other pair.When a watch movement is placed with its plate on the top surface of the3 lugs 20 a manipulation of the screws II and 22 will be made by thewatchmaker so that the plate will .be firmly gripped and positively heldwithout undue and injurious pressure being brought thereon.

What is claimed, is:

1. In a watch movement holder, a pair of rectangular plates arranged inparallel spaced relation, a screw extending centrally through saidplates, said screw being journalled for free rotation and held fromlongitudinal movement through one of said plates and having threadedengagement with the otherplate, a pair of jaw members for each plate,each pair of jaw members having confronting faces and slots extendingfrom these faces into the members, each plate having its ends fittinginto the slots of a respective pair of said jaw members, and a screw foreach pair of jaw members having a head portion freely revoluble in andheld from movement through one jaw member of the pair and havingthreaded engagement with the other member of said pair. a

2. In a watch movement holder, a pair of rectangular plates arranged inparallel spaced relation, a screw extending centrally through saidplates, said screw being journalled for free rotation and held fromlongitudinal movement through one of said plates and having threadedengagement with the other plate, a, pair of jaw members for each plate,each pair of jaw members having confronting faces and slots extendingfrom these faces into the members, each plate having its ends fittinginto the slots of a respective pair of said jaw members, a screw foreach pair of jaw members having a head portion freely revoluble in andheld from movement through one jaw member of the pair and havingthreaded engagement with the other member of said pair, and a pair ofguide rods fixed in one of said plates and slidably extending throughthe other'plate.

3. In a watch movement holder, a pair of rectangular plates arranged inparallel spaced relation, a screw extending centrally through saidplates, said screw being journalled for free rotation and held fromlongitudinal movement through one of said plates and having threadedengagement with the other plate, a pair of jaw members for each plate,each pair of jaw members having confronting faces and slots extendingfrom these faces into the members, each plate having its ends fittinginto the slots of a respective pair of said jaw members, a screw foreach pair of jaw members having a, head portion freely revoluble in andheld from movement through one jaw member of the pair and havingthreaded engagement with the other member of said pair, and an upwardlyextending lug projecting from the upper end of each jaw member andhaving a movement supporting face and angularly disposed movementgripping faces.
